The optical path is configured to pass sequentially through a first singlet, followed by the two doublets, and then a second singlet. This arrangement helps correct aberrations and improve image quality while maintaining a compact form factor. The system is likely intended for use in devices requiring precise imaging, such as cameras, microscopes, or other optical instruments, where minimizing size and weight is critical. The combination of singlets and doublets in this specific order optimizes light transmission and reduces distortion, making it suitable for applications demanding high optical performance in a constrained space.
4. The optical system of claim 1, wherein said image plane is an image plane of an image capture device.
The invention relates to an optical system designed to correct chromatic aberration in imaging applications, particularly for image capture devices. Chromatic aberration occurs when different wavelengths of light focus at different points, leading to color fringing and reduced image sharpness. The optical system includes a lens element with a specific refractive index profile that varies along its optical axis. This profile is engineered to compensate for longitudinal chromatic aberration, ensuring that light of different wavelengths converges at a common focal point on the image plane. The image plane is the sensor surface of an image capture device, such as a digital camera or smartphone camera, where the corrected light forms a sharp, color-accurate image. The lens element may be a single component or part of a larger lens assembly, and its design accounts for the dispersion characteristics of the materials used. By optimizing the refractive index distribution, the system minimizes chromatic aberration without requiring additional corrective elements, simplifying the optical design and reducing manufacturing complexity. This approach is particularly useful in compact imaging systems where space constraints limit the use of traditional multi-element correction methods. The invention improves image quality by ensuring consistent focus across the visible spectrum, enhancing both sharpness and color fidelity.
5. The optical system of claim 4, said image capture device comprises a controller configured to receive an image of said first spot and said second spot, wherein said controller is configured to determine if a total area of said first spot and said second spot is substantially one of a first area of said first spot and a second area of said second spot, the first spot is determined to be concentrically disposed with the second spot, otherwise, the first set of light rays is determined to not be parallelly disposed with respect to the second set of light rays.
This invention relates to an optical system for determining the alignment of two sets of light rays. The system addresses the challenge of verifying whether two sets of light rays are parallel by analyzing the spatial relationship between their projected spots. The optical system includes an image capture device that captures images of a first spot generated by a first set of light rays and a second spot generated by a second set of light rays. A controller processes these images to determine if the total area of the two spots is substantially equal to the area of either individual spot. If this condition is met, the controller concludes that the first spot is concentrically aligned with the second spot, indicating that the first set of light rays is parallel to the second set. If the condition is not met, the controller determines that the light rays are not parallel. This method provides a precise way to verify optical alignment without requiring complex mechanical adjustments or additional calibration steps. The system is particularly useful in applications where maintaining parallelism between light paths is critical, such as in optical communication, laser alignment, or precision measurement systems.

This invention relates to optical systems designed to enhance the visibility of angular deviations in light rays, particularly for applications requiring precise alignment or measurement. The system generates at least two sets of light rays, where at least one of these sets forms a cross-hair shape. The cross-hair pattern allows users to visually detect angular deviations in the light rays, improving accuracy in alignment or targeting tasks. The system may be used in optical instruments such as telescopes, surveying tools, or targeting devices where precise angular adjustments are necessary. The cross-hair shape provides a clear reference for alignment, making it easier to identify and correct deviations. The invention ensures that the light rays maintain their cross-hair configuration, ensuring consistent visibility of angular changes. This design is particularly useful in environments where small angular errors can significantly impact performance, such as in scientific measurements or military applications. The system may include additional components to generate or modify the light rays, ensuring the cross-hair pattern remains stable under varying conditions. The overall goal is to provide a reliable visual indicator for angular deviations, improving precision in optical systems.
